Re: MY POWER SUPPLY WENT 24VTry a 100 nano cap across the emitter to get rid of stray harmonics from TX put a 0.1 ohm 20w wirewound in the positive output line and that will give the trany time to react to larger spikes than originally designed for. If that doesn't help get back to me theres half a dozen more cheap mods to stop overvolting OK. John fb193.
